[Zope] absent variables

[Miha]

Hello all in,

   I meet problem, may be somebody can help me. I try to send results
   of filled form thought dtml-method (proxy of course), but user can
   don't fill some input values. When I submit form with unchecked
   checkbox (name favorite) I receive error:
          Error Type: Bad Request
          Error Value: ['favorite']

   How i can create default values for favorite?
   My SQL query for ZGadFlyDB:
         create TABLE REPORTS ( COUNTRY VARCHAR, REGION VARCHAR,
                                TOWN VARCHAR,    NAME VARCHAR,
                                ADRESS VARCHAR,  EMAIL VARCHAR,
                                TEL VARCHAR,     FAVORITE VARCHAR)

                                
   My code:
---[FORM::DTML-Document
<form name="startNewLife" method="post" action="reportAction">
